History of Friedrich II of Prussia, Volume 04 by Thomas Carlyle

In his seventh year, young Friedrich was taken out of the hands of the women; and had Tutors and Sub-Tutors of masculine gender, who had been nominated for him some time ago, actually set to work upon their function. These we have already heard of; they came from Stralsund Siege, all the principal hands.

Duhan de Jandun, the young French gentleman who had escaped from grammar-lessons to the trenches, he is the practical teacher. Lieutenant-General Graf Fink von Finkenstein and Lieutenant-Colonel von Kalkstein, they are Head Tutor (OBERHOFMEISTER) and Sub-Tutor; military men both, who had been in many wars besides Stralsund. By these three he was assiduously educated, subordinate schoolmasters working under them when needful, in such branches as the paternal judgment would admit; the paternal object and theirs being to infuse useful knowledge, reject useless, and wind up the whole into a military finish. These appointments, made at different precise dates, took effect, all of them, in the year 1719.
